ICANN: Proposed IDN Guidelines Revision

ICANN logoICANN is today publishing a proposed version 3.0 of the Internationalized Domain Name (IDN) Implementation Guidelines [PDF, 196 KB] for public comment. The IDN Guidelines are a list of general standards that all top-level domain registries deploying IDNs are required to follow based on the Internationalized Domain Names for Applications (IDNA) protocol standard from the IETF.

This draft was developed by the IDN Guidelines Revision Working Group (comprised of ccTLD and gTLD registry representatives with IDN experience supported by ICANN staff). The new draft modifies the current Version 2.2 to reflect the IDNABIS revision (“IDNA2008 protocol”) of the initial IDNA protocol (“IDNA2003”). ICANN previously published a discussion draft prior to the ICANN meeting in Cartagena, Colombia in November 2010 (see www.icann.org/en/announcements/announcement-4-15nov10-en.htm).

The current version of the IDN Guidelines is available at
